Maintenance testing is a subset of software testing focused on verifying that a software system continues to function correctly after modifications such as upgrades, patches, or bug fixes. Its primary goal is to ensure that recent changes have not introduced new defects and that the existing functionality remains unaffected, a practice often referred to as regression testing.

This type of testing is typically performed during the maintenance phase of the software development lifecycle. It involves rerunning previously executed test cases and may include additional tests tailored to the recent changes or specific areas of concern. Maintenance testing helps identify unintended side effects of modifications and confirms the stability of the software over time.

Common techniques used in maintenance testing include selective retesting, where only the impacted parts of the system are tested, and regression testing, which verifies that the existing functionalities are preserved. Automation tools are frequently employed to streamline repetitive test executions and improve efficiency.

Effective maintenance testing requires comprehensive test plans that identify critical areas, test cases, and escalation paths for issues detected. It plays a vital role in reducing the risks associated with system updates, supporting continuous delivery, and extending the lifespan of software applications.

Overall, maintenance testing is crucial for sustaining software quality in evolving systems. It ensures that updates and patches do not compromise system integrity and facilitates reliable, ongoing operation in response to changing requirements and environments.
